A toxic chemical used in hair products for black women fuels breast cancer, study finds:
Haircare and beauty products marketed to black women often contain a class of hormone-disrupting chemicals called parabens. According to a new study, those chemicals are not only linked to increased breast cancer risk, they uniquely fuel the spread of cancer cells in black women, compared to white women.
Parabens are a group of chemicals that keep mold and bacteria from growing on beauty products, thus prolonging their shelf lives. But, in humans, parabens can mimic the hormone estrogen, possibly fueling dangerous cell growth, according to research.
The study, which will be presented today at the Endocrine Society's annual meeting in Atlanta, analysed the effect parabens had on breast cancer cells from both black women and white women. Researchers found parabens increased the growth of black breast cancer cell lines, but did not effect white breast cancer cell lines at the same dose.
Parabens also increased the expression of genes linked to breast cancer in both black and white women.
"Black women are more likely to buy and use hair products with these types of chemicals, but we do not have a lot of data about how parabens may increase breast cancer risk in black women," Lindsey S. Treviño, the study's lead researcher, said in a press release. "This is because black women have not been picked to take part in most research studies looking at this link. Also, studies to test this link have only used breast cancer cell lines from white women."

I work in a food and beverage processing plant. Everything we make is USDA certified organic, tested, no preservatives, etc.
However, it turns out we're allowed to use many additives in very small amounts that don't have to be on the label. Those additives have been extensively tested as to being non-harmful in any way, but still, you might imagine that someone somewhere could have an allergy or sensitivity to something.
For the record, we do not use any of those, but it's possible the raw ingredients have something we don't know about. Very not likely though. No more than say wheat having some amount of insect bits.
The only one we ever even talked about using is an anti-foaming additive, but ended up not using it. If we had, it would be something like 28 cc in 8,000 liters of soda.
Soda can filling: can filled with carbonated soda, split-second later lid crimped on. Some batches and conditions caused soda to foam and you end up with cans not quite full to spec and get rejected and wasted (or workers take home).
TL;DR: US govt. FDA allows a very small amount of "stuff" that's not on the label in foods, drinks, and other human-contact things.

They believe in the safety (and ineffectiveness) of Homeopathy...
